AIIMS 2017 Biology Bryophytes MCQ Question
Read the following statements regarding bryophytes and choose the incorrect option.
Gametophytic phase is dominant in life cycle
Fertilisation takes place in presence of water
Zygote undergoes meiosis to produce sporophyte
Sporophyte is physiologically dependent on gametophyte
Correct Answer
Detailed Explanation
In bryophytes, the zygote undergoes mitosis, not meiosis, to develop into the sporophyte, which is a diploid structure that remains attached to and dependent on the gametophyte for nutrition. Option A is correct as the gametophyte is the dominant phase of the life cycle, while option B is also accurate since fertilization requires water (H₂O) for sperm motility. Option D is true because the sporophyte relies on the gametophyte for sustenance, illustrating the interdependence of these two phases in bryophyte reproduction.
